Indeed for live sound polarity matters very much - whether what comes out of the speakers is in the same acoustic polarity can make a big difference.

neither way sounds especially better.
There have been a number of studies regarding teh audibility of phase and polarity.
Regarding phase audibility, it's been shown that phase distorion could be heard when it changed significantly the crest factor of a complex signal.
Regarding polarity, I witnessed myself a case where two sound engineers diagnosed polarity reversal in loudspeakers, listening to a kick drum. They said "it sucks air, instead of pushing air". Thet were right, when correct polarity was restablished, the sound was better. I never had the possibility to investigate the issue.
